My son & I both have iPhone 12 and we are with spectrum. Spectrum runs off Verizon towers when we are home (which is often I work from home) every 30 Minutes I have to check my phone and turn it off and turn it back on. My service did the same thing. I’ve tried to reset I’ve tried everything I’ve been round and round with spectrum over it over nothing alleviates the problem per a recent forum that I read on Apple support it could be the iPhone 12 can somebody please reach out to me or let me know what the issue is I have tried everything that’s very frustrating
